Having played more of the alien commander lately, I have to say that I really don't enjoy it and the sole reason is Drifters. The marine comm was long ago freed from his worker units - he just drops things anywhere and players build them for him. MACs are just helpers now to make him a little more independent. The alien comm, on the other hand, still has to use a worker to build every single structure... And on top of that, it's a worker that sacrifices itself so he has to go grab a new one every single time. That's not fair no matter how you look at it. To be blunt, worker units in NS2 just don't handle very well and having to manage this many of them is tedious.
In my opinion, Drifters should be used for building RTs and Hives and occasional support stuff like Flare. Structures and upgrade chambers should be spawned from their corresponding hive like pustules, anywhere where there's connected infestation, and build slowly on their own. The alien comm should spend less time moving Drifters around and more time managing his chambers - controlling whips, deploying umbra/cloak, etc.
Maybe it's just me... Do you guys actually find that ordering these things around contributes positively to the alien comm's experience?
